Determine whether the function f(x)=4x^3 is even or odd

slega [8]

Answer:

Step-by-step explanation:

Answer:

odd function

Explanation:

To determine if a function f(x) is even/odd consider the following.

• If f(x) = f( -x) , then f(x) is even

Even functions are symmetrical about the y-axis.

• If - f(x) = f(-x) , then f(x) is odd

Odd functions have symmetry about the origin.

Test for even function

f(−x)=4(−x)3=−4x3≠f(x)

Since f(x) ≠ f( -x) , then f(x) is not even

Test for odd function

−f(x)=−(4x3)=−4x3=f(−x)

Since - f(x) = f( -x) , then f(x) is odd

as the schools sign language interpreter kiran gets paid 35.50 for every parent-teacher conference that he attends. He also gets

yKpoI14uk [10]

<u>The interpreter attended </u><u>22 parent-teacher conference</u><u> and </u><u>5 school related assembly</u>

To solve this problem, we would write out two set of linear equations.

The data given on this problem are

parent-teacher conference = $35.50
school related assembly = $42
The total number of engagements = 27

Let x represent the number of parent-teacher conference

let y represent the number of school related conference

<h3>Equations</h3><h3> $x+y = 27...equation (i)\\35.50(x)+42y=991...equation(ii)$ </h3>

From equation (i)

$x+y = 27\\x = 27-y...equation(iii)\\$

Put equation(iii) into equation (ii)

$35.50x+42y=991\\35.50(27-y)+42y=991\\958.50-35.50y+42y=991\\6.50y=991-958.50\\y=5$

Put y = 5 into equation 1

$x+y=27\\y = 5\\x+5=27\\x=27-5\\x=22$

From the above calculations, he attended 22 parent-teacher conference and 5 school related assembly.
